RT8097CHGB Richtek

RT8097C 2A, 1MHz, 6V CMCOT Synchronous Step-Down Converter General Description Features Efficiency Up to 95% The RT8097C is a high efficiency synchronous step- R 100m HS / 70m LS DS(ON) down DC-DC converter. Its input voltage range is from V Range 2.7V to 6V IN 2.7V to 6V and provides an adjustable regulated output V 0.6V with 1.2% Accuracy at 25C REF voltage from 0.6V to 3.4V while delivering up to 2A of CMCOT Control Loop Design for Best output current. Transient Response, Robust Loop Stability with The internal synchronous low on-resistance power Low-ESR (MLCC) C OUT switches increase efficiency and eliminate the need for Soft-Start 1.2ms PGOOD Function in SOT-23-6 an external Schottky diode. The Current Mode Power Saving at Light Load Constant-On-time (CMCOT) operation with internal compensation allows the transient response to be Applications optimized over a wide range of loads and output STB, Cable Modem, & xDSL Platforms capacitors. The RT8097C is available in the SOT-23- LCD TV Power Supply & Metering Platforms 5/6 package.

The RT8097C operates from a 2.7V to 6V input. Feedback voltage input. An external resistor divider from the output to 5 6 FB GND, tapped to the FB pin, sets the output voltage. Power good indicator. The output of this pin is an open-drain with external -- 5 PG pull-up resistor. PG is pulled up when the FB voltage is within 90%, otherwise it is LOW. Copyright 2019 Richtek Technology Corporation.
